Pervious Asphalt Roads and Parking Lots: Stormwater Design Considerations
Use of pervious asphalt requires creative stormwater design using available and adapted hydrologic and hydraulic modeling tools, highly integrated site design, and a coordinated design process. This is demonstrated by two very different Puget Sound area installations: Brickyard Park and Ride Lot Expansion, and Snoqualmie Point Community Park. Brickyard Park and Ride is an overcrowded park-and-ride lot on a constrained site requiring 200 additional spaces within a limited, suitable footprint. Snoqualmie Point Community Park is a new city park with an access road, turn-around, and parking for 23 vehicles on a sloped, wooded site. Conventional stormwater facilities (traditional pavement with underground vault) were considered for Brickyard Park and Ride Lot and found to be more expensive than pervious pavement with detention storage in the pavement section. At Snoqualmie Point Park, utilization of an integrated low-impact stormwater approach was a primary design goal, in keeping with the natural character of the surrounding area and park design. This paper presents the stormwater design considerations for both projects.
